I suspect that this dog is urinating all over this apartment.

As for sex offenders, I have a friend who in college got drunk and was arrested for public urination and was put on the sex offenders list --  he is currently a doctor. 

Your first hurtle is the zoning and partitioning a single deed+mortgage into two uniquely sellable units.  

You got past the first big hurtle in real estate investment, signing up and reaching out in BiggerPockets.

I affectionately refer to this prospect as the Pee House as it reeks of pet urine. 

Monitored the house, and found dogs locked up inside defecating and urinating for what appeared to be many days.

I bought the cat urine beat up dump no one wanted.

It was full of dog feces and urine, mouse feces and urine, and fly feces . 

The smell of dog urine and unreal amount of junk piled up everywhere was almost overwhelming but I focused on trying to see the potential and actually really enjoyed the process.So... the deal analysis:ARV: $210,000Rehab: $45,000 (this is somewhat of a "rough estimate". 

It seems like fair common sense that an additional 4 animals of the same type would not provide much addition emotional support however quadruple the chance that the landlord will end up with urine stains on their flooring.Its a bit of a free for all at the moment it seems.
